Suicide is a leading cause of death in early adolescents (i.e., children ages 11-14), underscoring the need for a more complex understanding of suicidality in youth. Syndemics framework posits that the overlap of multiple maladaptive behaviors (or risk factors) produces worse health outcomes compared to each behavior alone. The use of this framework in preventing suicide necessitates that identification of developmental risk factors that occur in tandem to suicide (e.g., disordered eating behaviors and substance use) may be important for intervening on those at greatest risk of suicide.
The present study uses latent class analysis (LCA) to evaluate the relationship between suicidality and disordered eating behaviors in early adolescence, and associations with other developmental risk factors in an epidemiological sample of middle school students (N = 3,811).
Lifetime prevalence ranged from 6.8% to 18.2% for suicidality, and 5.3%-48.7% for disordered eating behavior. Our final model identified six independent classes, and each class had differential associations with several additional developmental risk factors.
By pinpointing specific classes of individuals who may be at risk for multiple developmental risk factors, our results have important implications for public health intervention and prevention efforts for a wide range of adolescent risk behaviors, including suicidality.
自杀是青少年早期(即 11-14 岁的儿童)的主要死亡原因,这突显了需要更深入地了解年轻人的自杀倾向。综合征模式假设,多种适应不良行为(或风险因素)的重叠比每种行为单独发生产生更糟糕的健康后果。该框架在预防自杀方面的应用需要确定与自杀同时发生的发展风险因素(例如,饮食失调行为和物质使用),这对于干预那些自杀风险最高的人可能很重要。
本研究使用潜在类别分析(LCA)来评估青春期早期自杀倾向与饮食失调行为之间的关系,并在中学生的流行病学样本中(N=3811),评估与其他发展风险因素的关联。
终生患病率在自杀倾向方面为 6.8%至 18.2%,在饮食失调行为方面为 5.3%-48.7%。我们的最终模型确定了六个独立的类别,每个类别与其他几个发展风险因素都有不同的关联。
通过确定可能面临多种发展风险因素的特定人群类别,我们的研究结果对公共卫生干预和预防广泛青少年风险行为(包括自杀倾向)的努力具有重要意义。
